Description

The hdfcompressor tool copies a source HDF file and compress its SDS data, using a gzip algorithm.

Limitation

At this time, only the file/SDS attributes and SDS data are supported. The VData, VGroup… are ignored.

The build process supports only the UNIX/LINUX platforms

Usage

hdfcompressor infile outfile  [compression-level]
 
    infile  a valid and existing HDF file [REQUIRED]
 
    outfile path to the compressed output file [REQUIRED]
 
    [compression-level] gzip compression level, from 0 to 9 [OPTIONAL]. If not set, 6 is used by default

Compilation

Prerequisites

a C++ compiler
a HDF4 library ( http://www.hdfgroup.org/products/hdf4/ )

Environment

First, set the pathes to the HDF4 library by defining the environment variables

HDF_INC=<HDF4-includes-directory> , where <HDF4-includes-directory> contains the HDF4 library includes : hdf.h, mfhdf.h…
HDF_LIBDIR=<HDF4-libraries-directory>, where <HDF4-libraries-directory> contains the HDF4 libraries : libdf.a ( or libdf.so ), libmfhdf.a ( or libmfhdf.so )

If you are using the bash shell, this can be done via the export command :

> export HDF_INC=&lt;HDF4-includes-directory>
> export HDF_LIBDIR=&lt;HDF4-libraries-directory>

Of course, replace <HDF4-includes-directory> and <HDF4-libraries-directory> by the real pathes on your system.

Build

Build the application by running

> make

If successfull, the hdfcompressor tool will be situed in the bin directory. You can also use the library contained in the lib directory
